Prions are more like alien bio weapons

They eat our brains, give us Alzheimers and leave us unable to see the difference between our loved ones and aliens.




Life forms can be so spread out we don't notice.
THink of an ant colony where each tiny being acts in concert with the whole.

SImilar beings composed of seperate motes of intelligently controlled co oridination but so small, pervasive and spread out that we generally don't notice. Virus for sure, but think of beings a bit larger.
Even on a galactic scale...   The galaxy itself?
no the galaxies are but the connective tissue of one mote...

ooooooooooooo cool
